Definitions
- a high temperature resistant inorganic fiber that is useful as a thermal, electrical, or acoustical insulating material, and which has a use temperature of 1260°C and greater is provided.
- the high temperature resistant inorganic fiber is easily manufacturable, exhibits low shrinkage after exposure to the use temperature, retains good mechanical strength after exposure to the use temperature, and exhibits low biopersistence in physiological fluids.
- the low biopersistence fibers In addition to temperature resistance as expressed by shrinkage characteristics that are important in fibers that are used in insulation, it is also required that the low biopersistence fibers have mechanical strength characteristics during and following exposure to the expected use or service temperature, that will permit the fiber to maintain its structural integrity and insulating characteristics in use.
- One characteristic of the mechanical integrity of a fiber is its after service friability. The more friable a fiber, that is, the more easily it is crushed or crumbled to a powder, the less mechanical integrity it possesses. In general, inorganic fibers that exhibit both high temperature resistance and low biopersistence in physiological fluids also exhibit a high degree of after service friability. This results in a brittle fiber lacking the strength or mechanical integrity after exposure to the service temperature to be able to provide the necessary structure to accomplish its insulating purpose. Other measures of mechanical integrity of fibers include compression strength and compression recovery.
- an improved inorganic fiber composition that is readily manufacturable from a fiberizable melt of desired ingredients, which exhibits low biopersistence, low shrinkage during and after exposure to service temperatures of 1260°C or greater and, which exhibits low brittleness after exposure to the expected use temperatures, and which maintains mechanical integrity after exposure to use temperatures of 1260°C or greater.
- a high temperature resistant alkaline-earth silicate fiber exhibiting improved thermal stability when the inorganic fiber is exposed to elevated temperatures of 1000°C to 1500°C. It has been found that the addition of suitable amounts of strontium to an alkaline-earth silicate inorganic fiber reduces fiber shrinkage and enhances mechanical strength beyond that of examples without strontium oxide additions. Thus, the fiber exhibits low biopersistence in physiological solutions, reduced linear shrinkage, and improved mechanical strength after exposure to expected use temperatures.

- an inorganic fiber containing article comprising at least one of bulk fiber, blankets, blocks, boards, caulking compositions, cement compositions, coatings, felts, mats, moldable compositions, modules, papers, pumpable compositions, putty compositions, sheets, tamping mixtures, vacuum cast shapes, vacuum cast forms, or woven textiles (for example, braids, cloths, fabrics, ropes, tapes, sleeving, wicking).
- the fiber to be produced must be manufacturable, sufficiently soluble (ie, having low biopersistence) in physiological fluids, and capable of surviving high temperatures with minimal shrinkage and minimal loss of mechanical integrity during exposure to the high service temperatures.
- the present inorganic fiber exhibits low biopersistence in physiological fluids. By “low biopersistence" in physiological fluids, it is meant that the inorganic fiber at least partially dissolves in such fluids, such as simulated lung fluid, during in vitro tests.
- Biopersistence may be tested by measuring the rate at which mass is lost from the fiber (ng/cm 2 -hr) under conditions which simulate the temperature and chemical conditions found in the human lung. This test consists of exposing approximately O.lg of de-shotted fiber to 50 ml of simulated lung fluid (SLF) for 6 hours. The entire test system is maintained at 37°C, to simulate the temperature of the human body.
- SPF simulated lung fluid
- the SLF After the SLF has been exposed to the fiber, it is collected and analyzed for glass constituents using Inductively Coupled Plasma Spectroscopy. A "blank" SLF sample is also measured and used to correct for elements present in the SLF. Once this data has been obtained, it is possible to calculate the rate at which the fiber has lost mass over the time interval of the study.
- the fibers are significantly less biopersistent than normal refractory ceramic fiber in simulated lung fluid.
- Viscosity refers to the ability of a glass melt to resist flow or shear stress. The viscosity-temperature relationship is critical in determining whether it is possible to fiberize a given glass composition. An optimum viscosity curve would have a low viscosity (5-50 poise) at the fiberization temperature and would gradually increase as the temperature decreased. If the melt is not sufficiently viscous (i.e. too thin) at the fiberization temperature, the result is a short, thin fiber, with a high proportion of unfiberized material (shot). If the melt is too viscous at the fiberization temperature, the resulting fiber will be extremely coarse (high diameter) and short.
- Viscosity is dependent upon melt chemistry, which is also affected by elements or compounds that act as viscosity modifiers. Viscosity modifiers permit fibers to be blown or spun from the fiber melt. It is desirable, however, that such viscosity modifiers, either by type or amount, do not adversely impact the solubility, shrink resistance, or mechanical strength of the blown or spun fiber.
- One approach to testing whether a fiber of a defined composition can be readily manufactured at an acceptable quality level is to determine whether the viscosity curve of the experimental chemistry matches that of a known product which can be easily fiberized. Viscosity-temperature profiles may be measured on a viscometer, capable of operating at elevated temperatures. In addition, an adequate viscosity profile may be inferred by routine experimentation, examining the quality of fiber (index, diameter, length) produced. The shape of the viscosity vs. temperature curve for a glass composition is representative of the ease with which a melt will fiberize and thus, of the quality of the resulting fiber (affecting, for example, the fiber's shot content, fiber diameter, and fiber length). Glasses generally have low viscosity at high temperatures.
- the present fiber melt composition possesses a viscosity profile of a readily manufacturable fiber.
- Linear shrinkage of an inorganic fiber is a good measure of a fiber's dimensional stability at high temperatures or of its performance at a particular continuous service or use temperature. Fibers are tested for shrinkage by forming them into a mat and needle punching the mat together into a blanket of approximately 4-10 pounds per cubic foot density and a thickness of about 1 inch. Such pads are cut into 3 inch x 5 inch pieces and platinum pins are inserted into the face of the material. The separation distance of these pins is then carefully measured and recorded. The pad is then placed into a furnace, ramped to temperature and held at the temperature for a fixed period of time. After heating, the pin separation is again measured to determine the linear shrinkage that pad has experienced.
- the ability of the fiber to maintain its integrity after exposure to the use temperature may also be measured mechanically by testing for compression strength and compression recovery. These tests measure, respectively, how easily the pad may be deformed and the amount of resiliency (or compression recovery) the pad exhibits after a compression of 50%. Visual and tactile observations indicate that the present inorganic fiber remains intact and maintains its form after exposure to a use temperature of at least 1260 or 1400°C.
